Just a thought. No one has ever mass produced a Westinghouse box cab electric. I made this one using an old brass electric body, K-line power trucks and electronic and a Lionel pantograph. If you made a plastic body and used your Alco trucks it seems like the electric could be made for a reasonable price. These electrics ran all over the United States, Canada, and Mexico from the 1920s to the present.
